Patent CA-2015545-A1 (CA)
Inventor: KURITA KAZUHITO
IPC: G11B15/093
Filed: 1990-04-26
Abstract: A cassette tape recording and/or reproducing apparatus in which a single pinch lever pivotally supports a pair of pinch rollers corresponding to a pair of capstans rotatable in directions opposite to each other.  A head operating member such as a head base or the like is movable in a first direction in response to a play lever or a movement of the play lever, and can be moved in a second direction perpendicular to the first direction so that the pair of pinch rollers are alternately urged against the pair of capstans.  Tape guides and a head supporting portion are formed unitarily with the pinch lever at the position between the pair of pinch rollers, allowing the relationship between the pinch rollers, the tape guides and the head to be determined with ease, which becomes advantageous in forming the tape path.  Further, the number of parts can be reduced.

Title: Weight set connecting mechanism for subsea tubular members
Inventor: FARRELL THOMAS J
IPC: F16L37/08
Filed: 1990-12-06
Abstract: An improved mechanism for connecting tubular members in a subsea well in which the members are locked together in a preloaded condition. In the preferred form of the invention the loading is provided by a series of fingers mounted on the inner tubular member and flexing through a restriction in the outer tubular member during landing and then springing back from such flexed position to engage and wedge against a tapered shoulder at the lower end of the restriction to both lock the inner tubular member in its seated position and also to provide the preloading desired. In a second form, the inner member is landed on a ring which is engaged on the outer tubular member landing seat and then further lowering of the inner member moves a wedge on the inner member to cause the upper end of the ring to engage the internal profile of the outer member and the lower end to engage a lower external profile on the inner member and to be wedged therein to create the lock down and the desired preload. A third form utilizes a lower split landing ring, an upper split latching ring and a resilient loading support sleeve therebetween with a wedge on the inner member to set the split latching ring, in place of the single ring of the second form. The third form operates on the same principle as the second form.

A check valve (20) is provided in the filler tube (14) at the fuel tank (12).  The check valve (20) in the filler tube (14) features a valve element (38) having cylindrical sides (39) and a hemispherical end (41) which is received in a housing (32) having cylindrical walls (34) and an annular seat (40) against which the hemispherical end (41) of the valve element (38) seals.  The check valve (20) in the filler tube  (14)  is spring biased into a closed position  with  a  force  less  than  that  required  to automatically shutoff fuel dispensing.
